Dear Marko,<br>
<br>
you are right, the documentation is wrong here. Actually, we fixed
this in the .c file some time ago, but obviously forgot to adjust
the header file as well.<br>
<br>
Since variables can be present in different internal structures of
SCIP, it is not allowed to delete variables externally. What you may
do is to mark the variable to be deletable via
SCIPvarMarkDeletable() and change the parameters pricing/delvars and
pricing/delvarsroot to TRUE to let SCIP automatically delete
variables which are not needed anymore.<br>
<br>
Best,<br>

Dear All,<br>
<br>
I'm using SCIP 3.1.1 with SoPlex and I'm dealing with a
branch-and-price procedure. I would like to delete variables
during the procedure but when I call method <i>SCIPdelVar</i> I
get error message, because SCIP is in invalid stage.<br>
It surprised me since the documentation (both 3.1.1 and 3.2.0)
says <i>SCIPdelVar</i> can be called in stage <i>SCIP_STAGE_SOLVING</i>,
so I've checked the source code and it is clear that method can
not be called in this stage.<br>
<br>
So, I would like to notice, that documentation is probably not up
to date, and I would like to know if it is possible to delete
variables (or priced variables) in solving stage.<br>
<br>
Best regards,<br>
Marko<br>
